According to Stake (2005), the case study is not a research methodology, but a study of a
particular case, using any
desirable/relevant research methods (as cited in Thomas, 2011). The case, which is studied, can be an
institution, a project, a period, a person, an event, a decision, or any other
system. However, this case must be an instance of some class of cases,
identified by the researcher, which constitutes the study’s analytical
framework (Thomas, 2011). Hence, it can be argued that Chagnon’s (1983) participant-observation study of an
isolated South American tribe is a case study. After all, the particular case
here is the culture and social structure of a particular tribal society. While
tribal societies, peculiarities of their structures and cultures, and
particular approaches to studying them, clearly form Chagnon’s (1983)
analytical framework.
However,
this is not the whole story. In fact, according to Yin (2014), case studies are
appropriate for those instances where the research objective is to provide a
comprehensive and in-depth description of a social phenomenon (as cited in
Maul, 2015). But, what does this “social phenomenon” refer to? According to Yin
(2014), there are no clear boundaries between this “social phenomenon” (which
is to be explored by the case study) and its context (as cited in Maul, 2015); which
isn’t very helpful. So, a different approach is in order.
Thomas’
(2011) literature review, on what defines a case
in a case study, notes that a case can be a particular system, program,
institution, project, or policy in a “real life” context. It also notes that
cases are defined by boundaries around places and time periods (e.g. Germany
after World War I). In addition, according to George and Bennett (2005), the
studied case must be an instance of some class of cases, identified by the
researcher (as cited in Thomas, 2011). And Thomas (2011) refers to this class
of cases as a social phenomenon, which must comprise the study’s analytical
framework.
Hence,
it appears that Yin’s (2014) “social phenomenon” is not the case to be researched by the case study,
as may at first appear. Instead, it is simultaneously a class of cases, to
which the case to be studied must belong, and an analytical framework of the
study. However, it can still be argued that there are clear boundaries between
most classes of cases/analytical frameworks and their contexts; if only
because, otherwise they would not be identifiable.
